Remove unnecessary update_before_add from ZHA

Proposed change

Continuing the work on fixing ZHA initialization and while handling this comment: #70956 (comment) I discovered that several platforms were still calling update_before_add in ZHA which causes additional unnecessary network reads. The only place the update is needed is for group entities since their state is derived from the member states. This PR fixes the test comment above and corrects the extra network reads.

I am going to take an additional pass after the beta (for next months release) to verify all calls against all clusters in the tests to prevent something like this from happening again.
